Examples of org.apache.lucene.search.CachingWrapperFilter$FilterCache

org.apache.lucene.search.CachingWrapperFilter
Wraps another filter's result and caches it. The purpose is to allow filters to simply filter, and then wrap with this class to add caching.

    if (qb != null)
    {
      cachedFilter = new QueryWrapperFilter(q);
    } else
    {
      cachedFilter = new CachingWrapperFilter(f);
    }


    filterCache.put(cacheKey, cachedFilter);
    return cachedFilter;
  }
